IMPROVEMENT IN GRAlN-BINDERS.

Specification forming part of Letters Patent No. 190,993, dated May 29,1877; application filed June 8, 1876.

To all whom it may concern:

Be it known that we, NICHOLAS WERTS and JOHN G. GILMER, of Concordia, inthe county of Cloud and State of Kansas, have invented certain new anduseful Improvements in Grain- Binders; and we do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification, and in which-- Figure 1, Sheet 1, is a side elevation ofour improved grain-binder; Fig. 2, a plan view thereof; and Figs. 3, 4,and 5 are detached views of the same. Fig. 6, Sheet 2, is a view of theband made by our machine; and Figs. 7 and 8 are views of the twister.

Corresponding parts in the several figures are designated bylikeletters.

This invention relates to a certain improvement in grain-binders; and itconsists of the construction of the twister of the mechanism forreceiving or holding and rotating the gavel; and of the combinationtherewith of the twister and its operating mechanism, substantially ashereinafter more fully set forth.

In the annexed drawing, A refers to a frame, to which is hinged a tableor leaf, B, to receive the gavel to be bound. In the table. or leaf B isa curved lever or book, b, the function and operation of which will behereinafter described.

G is an oblong or other suitably-shaped disk, secured to an axis orshaft, 0, bearing in the frame A, and rotated by a belt or other mediumdriven by gearing upon the reaper or harvester. The ends of this diskare recessed, to conform to the openings in circular clamps D D adjustedtherein. The clamps D D are retained in the disk 0 by flanges d d upontheir peripheries entering grooves in the disk. These clamps are eachformed in two parts, hinged together at one side, and sprung openautomatically to receive the gavel, when occupying the positionindicated in Fig. 1, by the springs d d. It is when the clamps aresprung open the curved lever or hook b is brought into use, the hook orlever at this juncture being struck at its inner end by a pin orprojection, 0, upon the disk 0, causing its forward end, across whichthe gavel upon the table B has been placed, to throw the gavel into theopen clamp. As the disk 0 continues to revolve in the direction of thearrow, the open clamp with its gavel will be closed by contact with thetoothed segment E in the frame A, the end of the disk 0 having the openclamp approaching the said toothed segment until the clamp is closed,after which that end of the disk will maintain the same distance fromthe said segment. The clamp, with gavel at the opposite end ofthe disk0, when the open clamp has been closed, will have reached the lowerextremity of the toothed segment E, and be sprung open and release ordischarge its bound gavel, and ascend in an open position above thetable or leaf B to receive a second gavel for binding. Upon theperipheries of the clamps D D are teeth or cogs gearing with the teethor cogs of the segment E, by which an independent rotary movement isimparted to the said clamps for rotating the gavels. F is the twister,having its axis bearing in a journal-box, secured to the disk 0 inproximity to the open clamp and a beveled cog-wheel, g, upon the disk,shaft, or axis 0, by which the twister is rotated to perform thetwisting of the straw to make the band, a beveled gear-wheel, g, uponthe axis of the twister, gearing with the gear or cog wheel 9. Aduplication of this mechanism is used in connection with the clamp atthe opposite end of the disk in binding two bundles or gavelssimultaneously or alternately.

The twister F in its general outline is the frustum ot' acone,which hastwo spiral grooves, ff, winding around the cone in opposite directions.Surrounding the grooved cone or twister proper is a casing,f conformingto the shape of the cone, and having an opening, f out through which theends of the straws in the grooves of the twister or cone to form theband may project to avoid crowding, 85c.

The casing f 1 does not partake of the rotary motion of the cone, itbeing fastened to the bearing of the axis of the cone or twister proper.Pivoted alongside of the orifices of .the spiral groovesff, and slightlyoverhanging the same, are triangular or other suitably-shaped cams h h,having their outer ends in contact with springs or plates ii fastened tothe periphery of the cone, and having their free ends partially closingthe entrances to the grooves f f.

This mechanism prevents the crowding of the grooves, as it will be seenthat, should more straw be taken up by the twister than will becontained in the grooves, the surplus or excess will press against theplates or cams h h, which, in turn, will press the springs ii outwardly,enlarging the entrances to the grooves, and allow the excess or surplusof straw to escape. Attached at one end to the casingf, and overhangingthe outer end of the twister or cone, is a bow, G. The gavel being inposition in the clamp or clamps, and receiving a rotary motion, and thedisk having the clamps a like motion, and the twister also rotated, thefree end of the how will take up straws from below the head of thegavel, small portions of which will be caught alternately by the h 'oksor points at the entrances of the grooves ff in the cone. The strawsthus caught will be twisted over each other toward the butts thereof bythe rotary movement of the cone F, and carried around the gavel by therotary movement of the gave], and this process continued until the bandencircles the gavel one or more times, when the gavel is released fromthe clamps D D, and the twister F then ceasing to engage straws, thetwisted portion of the straw last released from the twister F is thrustinto the gavel,

and the end of the band secured in place by mechanism not deemednecessary to be here described.

Having thus described our invention, what we claim, and desire to secureby Letters Patout, is-

1. The twister F, consisting of a grooved cone, having the orifices ofits grooves provided with cams h h and springs 13 i, substantially asshown and described, and for the purpose set forth.

2. The twister F, composed of the double grooved cone and bow G,attached to a casing, f, encircling the cone, substantially as and forthe purpose set forth.

3. The disk 0, having the cogged clamps D D, rotated by and incombination with the toothed or cogged segment E, substantially as andfor the purpose set forth.

4. The disk 0, having the cogged clamps D D and cogged or toothedsegment E, in combination with the table B, having the curved lever orhook b, operating in conjunction with the disk 0, substantially as andfor the purpose set forth.

5. The twister F, having its axis provided with a gear-wheel, g,cog-wheel g, and axis or shaft 0, in combination with the disk 0, havingthe cogged clamps D D and toothed segment E, substantially as and forthe purpose set forth.

In testimony that we claim the foregoing as our own we hereunto affixour signatures in presence of two witnesses.
